IMPROVEMENTIN wmnMILLs.

Speciifaticn forming part of Letters Patent No. 162.225, dated April 20,1875 g application filed February 8, 1875.

To all whom it may concern Be it known that I, MYRON GORE, of Ottawa, inthe county of La Salle and State of Illinois, have invented certainImprovements in Windmills, of which the following is a specification;

The first part of my invention relates to a novel construction oftheframe ot the Wheel of a Windmill, of the class known as selfregulatingsection rose-Wheels,7 and consists in a cheap and superior manner ofconstructing the said frame, so that the jarring and vibrating of themill, while at Work, will not be likely to shake the frame apart.

The second part of my invention consists in the combination, with thesections ot' a wind-Wheel of the above-named description, of levers andsprings, in such a manner that the section of a nheel, when depressed bya strong Wind, shall be speedily and surely brought back again when thewind slackens; the object of this part of my invention being to cheapenthe construction ofthe mechanism accomplishing this result, and also tomake the Wheel more reliable in its action, and more perfectlyself-regulating than it has been heretofore.

Figure l in the drawing, is a side elevation of a machine embodying myinvention. Fig. 2 is a vertical transverse section, showing those partsofthe machine which are at the.

left hand of the line a; a", drawn across Fig. l. Figs. 3, 4, 5, 6, and7 are detached pieces.

The timbers A A A are Well joined at the places Where they meet, andbolted onto the radial arms B B B, by placing between and at each cornera casting, O, (Figs. 5, 6, and 7,)

which forms a double socket, and has two bolt-holes, through which thetimbers A A A and B B B arc bolted together. This produces a very strongframe, offering resistance against strain not only from one side butfrom all sides, the casting or angle-piece C forming in this arrangementthe most important part. It will be observed that by this method ofconstructing the frame the sections K K K can be hinged at a distancefrom their ends, instead of directly at their ends, as Was the formerpractice, so that there is less danger of the force ofthe Wind breakingasection-bar, P. D is a loose collar or disk on the shaft E, and has init holes into which are hooked the rods F F F, and these rods are hingedat their outer ends to the sectionbars I P P, in such a manner that,when from increased speed or pressure of Wind the seotionsK K K arethrown out from their plane position, the collar D is made to slightlyrotate on the shaft E. In doing so, the levers LL L (Figs. 3 and 4) aredepressed by pins m m m on the outside of collar l). The depression ofthe levers L L L causes the springs M M M to be compressed in such amanner that, when the pressure of the Wind or the speed of the Wheelrelaxes, the levers L L L, through the springs M M M, cause the collar Dto turn back, forcing back the rods F F F, which in turn push back thesections K K K'into their level position, fiat against the face of thewheel. The collar D has also on it a raised part at N, on which a brakeis applied through the lever O, but this part I do not claim as myinvention.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

l. The castings O O C, forming doublesockets, in combination with radialarms B B B, and the timbers A A A, substantially as and for the purposesdescribed.

2. The levers L L L, and springs M M M, in combination with the loosecollar D, the rods F F F, and the sections K K K, substantially as andfor the purpose described.
